Abstract
Introduction

Most authors agree that surgery is the treatment of choice for benign tumours of the parotid gland. However, the best surgical technique and the extent of surgery remain controversial. This study attempts to establish whether the implementation of a partial superficial parotidectomy (PSP) is appropriate for the treatment of benign parotid gland tumours.

Material and methods

We selected 63 patients with benign parotid gland surgery, of whom 43 had a pleomorphic adenoma and 20, a Warthin tumour. Of this group of 63 patients, 6 could not be included. We consequently studied 57 patients, 41 of them diagnosed as pleomorphic adenoma and 16, as Warthin tumours. In all of them, a PSP was performed without intraoperative monitoring of the facial nerve.

Results

Transient facial nerve paralysis, 14 patients (24.5%). Ten cases were resolved within the first month after surgery and 4 before the third month, after indicating facial physiotherapy. One patient (1.7%) had a permanent difficulty in keeping one side of the lower lip aligned under pressure-mobility, without altering commissure mobility. None of the patients studied had a recurrence (control, 3–13 years).

Conclusions

Although PSP is a technique with a few complications, it has a recurrence rate comparable to or lower than other techniques used for the treatment of pleomorphic adenomas or Warthin parotid tumours. Intraoperative facial nerve monitoring can be helpful during surgery. The lack of monitoring would not be considered a contraindication for surgery.

Resumen
Introducción

La mayoría de los autores aceptan la cirugía como tratamiento de elección para los tumores benignos de parótida. La mejor técnica quirúrgica o el grado de extensión de la cirugía permanecen controvertidos. El presente estudio pretende comprobar si la parotidectomía parcial superficial (PPS) es adecuada para el tratamiento de los tumores benignos de glándula parótida.

Material y métodos

Seleccionamos 63 pacientes con tumor benigno, operados de glándula parótida, 43 tenían un adenoma pleomorfo y 20 un tumor de Warthin. De este grupo de 63 pacientes no se pudo incluir a 6 (3 fallecidos y 3 no localizados). Estudiamos a 57 pacientes, 41 diagnosticados de adenoma pleomorfo y 16 de tumores de Warthin. En todos ellos realizamos PPS sin monitorización del nervio facial.

Resultados

Parálisis transitoria del nervio facial 14 pacientes (24,5%). Diez se resolvieron antes del primer mes y cuatro antes del tercer mes. Un paciente (1,7%) sufrió una dificultad definitiva para mantener alineado el hemilabio inferior en la movilidad forzada, sin alteración en la movilidad de la comisura. Ninguna recidiva (control entre 3 y 13 años).

Conclusiones

La PPS es una técnica con unas complicaciones y una tasa de recidivas comparables o menores que otras técnicas empleadas para el tratamiento de adenomas pleomorfos o tumores de Warthin parotídeos. La monitorización del nervio facial puede ser una ayuda durante el acto quirúrgico. La falta de monitorización no sería considerada una contraindicación para la realización de la cirugía.
